Conductors and Insulators
Understanding the basic principles of electricity will help you understand and relate to how our nervous system works. The nervous system is quite literally an electrical system, and it obeys all the same principles of electricity that your test circuit does. Electricity must flow in a loop. The direction electricity flows in is from negative to positive, and electricity flows through conductors and is held back by insulators. Did you know that your nerves have a positive and a negative end? Wow!

Lab Materials Needed
Electricity Koa STEMCrate
- 3 whiney wires per student
(100 clip wires)
- 1 Nova Light per student
(30 Lights)
- 2 paper clips per student
- 1 rubber band per student
- Various materials to test for conductivity
-Teacher Demo and smart board illustrations below
Build your Test Circuit
You will need:
One Battery
one rubber Tube
2 paper clips
three Whiney Wires
one Nova (Light)
And Various test materials
Microscope Observation
Peripheral nerves are a lot like computer cords
TEacher Class Demo of Salt Water Conductivity
Build this circuit
Attach Whiney to the paper clips
* If your Teacher Demonstration Circuit does not work, check the following:
- Try Testing the circuit with one battery to make sure you can light the bulb.
- Add a second AA battery to your circuit. If the bulb does not light, your battery might be wired backwards. swap the leads on one of the batteries. Batteries are connected with opposing + and - terminals. You will need two batteries to use the circuit in salt water.
- Make sure battery leads fit tightly - You may need to wiggle the paperclips to adjust for a good connection.
Salt (NaCl) is made of Sodium (Na) and Chlorine (Cl). Sodium is a metal, and when salt is dissolved into water, the sodium particles cause the water to conduct electricity. Our body uses the Sodium from salt to make our nervous systems work. The tiny bubbles you see are hydrogen gas made from breaking the bonds of water when the electricity passes through it.
